If it's tea-bag tea then it
has to be tea first, milk second, to regulate the desired colour - a nice rich brown.
Tea-pot tea, then either is fine.
If anybody is looking to really looking to p*** me off real proper, then: take a mug, pour some milk in, throw a tea bag in, fill the mug with hot water, chuck a spoon in, give it to me, and walk away
One of my fussy old bat habits is drinking from a white mug/cup. Nice clean contrast between the rich brown tea and the white
porcelain ceramic wall of the mug.
I can't stand tea in dark coloured cups, the colour of mug kind of camouflages the tea.
It doesn't taste the same out of a dark mug either.
Think my grandmother lies at the heart of all this nonsense somehow.
